From: PSI-Systems [mailto:PSI-Systems-hi6Y0CQ0nG0@public.gmane.org] and its still in the newest rc1-release! please can anyone help me in fixing this? ACPI: Found ECDT ACPI: Could not use ECDT
Your BIOS is broken. We just started looking at the EC_ID field in the ECDT, and unfortunately your machine's is wrong. A little explanation... Your laptop has an Embedded Controller. The ECDT table is supposed to describe the EC, so that AML can use operation regions in the EC before the EC device is actually found by the walking of the namespace. The ECDT-enumerated EC and the EC in the namespace are linked because there is a field (EC_ID) in the ECDT that gives the path to the EC in the namespace. If this is wrong, then we abort. As with so many things ACPI-related, the *right* answer is that IBM fixes their BIOS...but since this works under Windows, we may end up applying a yet-to-be-devised workaround. :( Regards -- Andy ------------------------------------------------------- This SF.net email is sponsored by: ApacheCon, November 18-21 in Las Vegas (supported by COMDEX), the only Apache event to be fully supported by the ASF. http://www.apachecon.com
